So I'm back. Little bit more detail on the panel.
-I actually liked the deleted scene because it takes place right after when the Boob Lady shows Homer which way to go, and right before you see him climbing the rocks to take a look at domed Springfield. The way it was cut, I thought it created a plot hole; I mean, the Boob Lady just points him to somewhere, all the way in Alaska, and two seconds later he's at Springfield, with no apparent help? Didn't cut it for me.
-The Simpsons Ride is taking the place of the Back to the Future Ride, if you were wondering what kind of ride it was gonna be.
-I asked them the question about the showrunner replacing, and actually preceded it with "First of all, I'm here on behalf of the No Homers Club, so this question is from all of them.", and they all groaned and Matt said, "heeere it comes..."
Basically, they're very happy with what Al Jean's doing right now, and don't plan on switching showrunners for a long time.
-If this wasn't already known, they kinda addressed the post-classic trend of completely unrelated first acts seguing into the main plot. Al Jean pretty much openly stated that they were running out of ideas for one full plot, but they had these small ideas they thought were funny that could be used for one act, so voila, there's your reason why. They called it a "plot twist" of sorts.
-They've already recorded the DVD commentary for the Simpsons Movie, about a week or so ago.
I think there's one more thing I wanted to mention, but it slipped out of my mind. It'll come later, so whatever.
